This is a really well made shield for Arduino Uno. It fits very snugly onto a Uno board. Some effort is required to remove it from the Uno, though. This may or may not be an issue depending on how often you plan on removing the shield.

Great Shield
This is one of the better prototyping shields. The DIP pads make it way easier to build with than running wires for every component. Lots of 5v and GND connections.
